The purpose of this study is to assess doses to ¹⁸F-FDG, a radioactive drug, during PET examinations, to alleviate anxiety about radiation in patients and carers, to minimize the indiscriminate examination progress caused by medical institution personnel and space clearance problems, and health examination. The dose assessment was measured using a thermo-fluorescent dosimeter (TLD) and an electronic personal dosimeter (EPD) at the location of the cervical (hypothyroid), thorax (heart), and lower abdomen (breeding line) which are the three highest tissue areas of the radiation tissue weighting. In addition, spatial dose rates and radioactivity in urine were measured using GM counters and ion boxes. The results are as follows: First, the personal dosimeter TLD was measured 0.0425±0.0277 mSv in the cervical region, 0.0440±0.0386 mSv in the thorax and 0.0485±0.0436 mSv in the lower abdomen, with little difference in the heart dose depending on radiation sensitivity. The EPD was measured at 0.942±0.141 mSv/h immediately after the cervical position, and 0.192±0.031 mSv/h after 120 minutes. Immediately after the thorax position, 0.516±0.085 mSv/h, 120 minutes later 0.128±0.040 mSv/h. Immediately after the lower abdomen position, 0.468±0.091 mSv/h, and after 120 minutes 0.105±0.021 mSv/h were measured. The spatial dose rate at the GM counter was measured immediately at 0.041±0.005 mSv/h, 120 minutes later at 0.014±0.002 mSv/h. The radioactivity in urine using ion chamber was measured at 0.113±0.24 MBq/cc after 60 minutes and 0.063±0.13 MBq/cc after 120 minutes. As a result, ¹⁸F-FDG should be administered, dose re-evaluated two hours after the PET test is completed, and caregivers should be avoided. In addition, it is deemed necessary to provide patients and carers with sufficient explanations and expected values of exposure dose to avoid reckless testing. It is hoped that the data tested in this study will help patients and families relieve anxiety about radiation, and that the radiation workers' exposure management system and institutional improvements will contribute to the development of medical radiation.

This study aimed to investigate the effects of learning with role-playing on student satisfaction and achievement regarding behavior management teaching in pediatric dentistry. 93 students were divided into 19 groups and randomly assigned to role-play as a doctor, patient, parent, assistant, or narrator. Their performances were evaluated by the instructor and the satisfaction survey was conducted. All participants took the written test and were asked to compare lecture and role-playing with regard to the effectiveness of learning. Statistical analysis was performed with Mann-Whitney U test, Independent T-test, and Kruskal-Wallis test. 68 students (73.1%) who believed that the role-playing was more helpful than lecture showed higher level of satisfaction than students who believed lecture was more helpful. But there were no differences in the tutor evaluation score and the written test scores. Participants in the patient management scenario showed higher level of descriptive question scores of the written test and tutor evaluation score than those who participate in the parent management scenario. There were no differences between the role groups. Role-playing may help students to become more interested and participatory in learning behavior management. The level of satisfaction may differ by the design and content of the scenario.

Occupational therapist is required for patient-centered approaches to actively seek the perspectives of patients and their families in clinical settings. The purpose of this study was to investigate the current trends and to suggest future-oriented view of examination and assessment used by neurological occupational therapist in clinical settings. Sixty-six occupational therapists who work in persons with neurological disorders participated in this study. The survey was measured from Seoul and GyeongGi by means of E-mail about commonly used assessment tools and selecting considerations. The participants were 66 neurological occupational therapists. The number of patients by one day was from 10 to 14 persons, and the length of time for initial evaluation was 20-40 minutes per one patient, and reexamination periods was every 1 month or as functional changes were detected. The using tool was not limited only neurological tools, and choice consideration was the reliability and validity of clinical measures. The most frequently used tools for adults were: JHFT for motor function in upper extremity, MMSE-K for cognitive perceptual assessment, MBI for daily activity assessment, and COPM for occupational performance. The most frequently used tools for child were: MVPT for cognitive perceptual assessment and Wee-FIM for daily activity assessment. The results of this study suggest that it is necessary to integrate and associate patient-report, care-giver report, and results of performance-based assessment for estimating plan of care more quality.

A safety management rule of the diagnosis radiation system which opened a court 2006 February 10th was promulgated for safety of the radiation worker, patients and patients' family members. The purpose of this study is to minimize injury by radiation that can happen to patients and people around a sick ward when managing mobile X-ray system. This study analyzed sickroom environment of mobile X-ray examination and the statistical data of the Konkuk medical Information System(KIS) and the Picture Archiving Communication System(PACS). This study also investigated patient conditions, infection, relation information and related data, when the sickroom mobile X-ray examination is used. Through data analysis, many problems were expected such as restriction of space side, manpower and expense of business side, satisfaction degree decline of patient and protector of operation side. Therefore, we tried to restrict examination of multi bed sickroom, and to use treatment room in each ward to solve problem mentioned. As a result, the whole sickroom mobile X-ray examination rate decreased to near 50%, and mobile X-ray examination rate for inpatients decreased to more than 85%. This study shows that several attempts we did should be helpful for manpower, patients satisfaction and expenses. Also, they should protect patients in sickroom from unnecessary radiation exposure and could minimize inconvenience of patients and their family members from x-ray examination.

Purpose : Theophylline has recently been reported to have concurrent anti-inflammatory effects at low therapeutic plasma concentrations which are below the doses at which significants, clinically useful bronchodilatation is evident. Sustained-release formulation in capsule and dry syrup forms were developed to reduce its adverse effects and improve its clinical effects. We compared the therapeutic effects of theophylline dry syrup and capsules in children with mild asthma. Methods : Ninety children with mild asthma were randomized to receive either theophylline dry syrup (n=44) or theophylline capsules (n=46); 4 mg per kilogram of body weight, twice a day, for 12 weeks. Baseline and serial measurements of daytime and nighttime asthma symptom score were performed. Compliance scores, drug swallowing scores, and drug usability scores were measured every 4 weeks. Each scoring was rated on a scale of 0-4. Serum theophylline concentration were measured at 4 and at 12 weeks. To examine the anti-inflammatory effect of theophylline on asthma, Serum eosinophilic cationic protein as a marker of airway inflammation caused by eosinophil was measured 12 weeks pre- and post-administration. Results : The daytime and nighttime asthma symptom scores of the two groups after 4 weeks significantly improved over the baseline score. Daytime and nighttime asthma symptom scores in the dry syrup group were statistically lower at all time points except for the nighttime symptom scores at 4 weeks. Compliance scores, drug swallowing scores, and drug usability scores in the dry syrup group were significantly higher at the end time point. Only in the dry syrup group was the serum ECP at the end time point statistically lower than baseline. Conclusion : Low-dose sustained-release theophylline may be safe and effective in bronchial asthma and this effect may be mediated by its anti-inflammatory action mechanisms. Especially, when used in children with asthma, dry syrup formulation is recommended because of its higher compliance than capsule formulation.

As modern science is developed and advanced, examination and number of times using radiation are increasing daily. General diagnostic X-ray generator is installed on stationary form, But X-ray generator was developed because patient who is in the intensive care unit, operation room, emergency room can not move to general x-ray room. What we examine patient by x-ray generator is certainly necessary, So patient exposure is inevitable. but reducing radiation exposure is highly important matter about radiation technology, guardian, patient in the same hospital room, nurse etc. For this reason, rule regarding safety control of diagnostic x-ray generator revised for radiation worker, patient and protector proclaim that mobile diagnostic x-ray shield must placed in case of examine different location excluding operation room, emergency room, intensive care unit. But, radiogical technologist is having a lot of difficulties to examine with mobile x-ray generator, diagnostic x-ray shield partition, image plate and lead apron. So, when we use x-ray generator, we manufacture shield tools can be attached to the mobile x-ray generator On behalf of x-ray shield partition and conduct analysis and in comparison to part of body and distribution of dose rate and find way to reduce radiation exposure through distribution of dose rate of patient within the radiogical technologist, medical team. Mobile x-ray generator aimed at SHIMADZU inc. R-20, We manufactured equipment for shielding x-ray scattered x-ray by installing shielding wall from side to side based on support beam on the mobile x-ray generator. Shielding wall when moving can be folded and designed to expand when examine. Experiment measured five times in each by an angle for dose rate of eyes, thyroid, breast, abdomen and gonad on exposure condition of upper and lower extremity, chest, abdomen which is examined many times by mobile x-ray generator. We used dosimeter RSM-100 made by IJRAD and measured a horizontal dose rate by body part. The result of an experiment, shielding decreasing rate of the front and the rear showed 77 ~ 98.7%. Therefore using self-production shielding wall reduce scattered x-ray occurrence rate and confirm can decrease exposure dose consequently. Therefore, through this study, reduction result which is used shielding wall of self-production will be a role of shielding optimization and it could be answer about reduction of medical exposure recommended by ICRP 103.
